Sybase IQ

To create a PDM with support for features specific to the Sybase AS IQ DBMS family, select the appropriate version in the DBMS field of the New Model dialog. To view these extensions to the PowerDesigner metamodel in the Resource Editor, select Database > Edit Current DBMS and expand the Profile node.

Note: The DBMSs for Sybase IQ v12.0-12.6 are deprecated.

The following sections list the extensions provided for IQ.

Note: We do not provide documentation for the properties on the Physical Options and certain other tabs, though minimal information is available for them in the Resource Editor. For information about these properties, consult your DBMS reference documentation.

Reference Architecture Modeling (IQ)
PowerDesigner provides a special EAM model to help you determine the architecture required to deploy a Sybase IQ data warehouse solution to meet your anticipated workload. An advisor wizard generates architectures based on one or more hardware servers, and comparison tools help you choose the best architecture based on your requirements for cost and speed.
Information Lifecycle Management (IQ)
Sybase IQ v15.0 and higher provides data placement capabilities and supports hierarchical storage management with relocation of less critical data to cheaper storage. PowerDesigner offers a simple modeling structure to cost effectively manage "aging" of data inside the data center from 1st tier high performance storage for frequently accessed data through 2nd tier near-line storage for data that is infrequently accessed to 3rd tier archive storage for data that must remain available for regulatory audits.
Events (IQ/SQL Anywhere)
Sybase IQ (v12.7 and higher) and SQL Anywhere (v10 and higher) support events, which allow you to automate and schedule actions. PowerDesigner models events as extended objects with a stereotype of <<Event>>.
Dbspaces (IQ)
Sybase IQ distributes user data across multiple disks at the application level by representing each device as a dbspace. A dbspace can be an operating system file or a raw disk partition. Dbspaces can contain both user data and internal database structures used for startup, recovery, backup, and transaction management.
Table and Column Partitions (IQ)
A partition is a physical division of the contents of a database table, based on values in the column designated as the partition key, and allocated to a particular dbspace. You can override the allocation of values in certain columns by specifying column partitions.
Multiplex Servers (IQ)
Sybase IQ v15.0 and higher supports multiplex, a highly scalable shared disk grid technology that allows concurrent data loads and queries via independent data processing nodes connected to a shared data source.
Login Policies (IQ/SQL Anywhere)
Sybase IQ (v15.0 and higher) and SQL Anywhere (v12 and higher) define the rules to be followed when establishing a user’s database connection in a database object called a login policy. PowerDesigner models login policies as extended objects with a stereotype of <<LoginPolicy>>.
Remote Servers (IQ)
Sybase IQ v15.0 and higher supports remote servers, which define where remote objects mapped to a local proxy table are located. PowerDesigner models remote servers as extended objects with a stereotype of <<RemoteServer>>.
External Logins (IQ)
Sybase IQ v15.3 and higher supports external logins, which are alternate login names and passwords that are used when communicating with a remote server. PowerDesigner models external logins as extended objects with a stereotype of <<ExternLogin>>.
Spatial Data (IQ/SQL Anywhere)
Sybase IQ v15.4 and higher and SQL Anywhere v12 and higher can store spatial data (data that describes the position, shape, and orientation of objects in a defined space) using spatial reference systems.
Full Text Searches (IQ/SQL Anywhere)
Full text search can quickly find all instances of a term (word) in a database without having to scan table rows and without having to know which column a term is stored in. IQ (v15.2 and higher) and SQL Anywhere) support full text searches through text configurations and text indexes, which store complete positional information for every instance of every term in every indexed column.
Indexes (IQ)
Before creating IQ indexes, you should consider the implications of various types of indexes on the database server memory and disk space. The set of indexes you define for any given column can have dramatic impact on the speed of query processing.
Join Indexes (IQ/Oracle)
A join index is a special type of index, which represents a full outer join of two or more tables, where all rows from both tables are included in the result (with NULL returned for any column with no matching value). The query engine may use this full outer join as a starting point for queries that include left outer, right outer, and inner joins.
Generating IQ Data Movement Scripts
PowerDesigner provides the capability to generate data movement scripts to populate your AS IQ data warehouse from your other databases.
